Customer Reviews for the Atmos 65 (Spring 09) Osprey Packs Backpack

Trent R. - December 4, 2009

Excellent bag!
The best part is that you can use the side compression straps to reduce the thickness of the pack if you don't need so much space, so it can be a great overnight pack, or a great week-long-adventure pack.

Great Pack!
I just used this pack on a 4 day 42 mile Isle Royale trip and was very impressed. The ability to organize your gear is outstanding due to the numerous compartments. The comfort was great with 35lbs, no complaints. Highly recommended!

James D.vonLintel - March 27, 2009

Nice fit!
All the structures are quite nicely arranged, and rooky enough. I like the torso constructure with the webbing. I also like the color. The adjustable strapes are quite beneficial. The waist belt is the neatest with the areated construction.

Anon. Shopper - April 8, 2008

A great organizer bag
The tall version really fits my 6' 2" frame well, hip belts snug down securely and the belt pockets take a small a camera, sunscreen, lip balm and a half pound bag of trail mix. The option for hydration bladder inside or outside (in mesh area) works well and increases the internal volume, which is limited for rigid objects due to the curved suspension system. Don't expect to get any size bear proof container inside this bag. I used it all winter, with snowshoes, ice ax and crampons strapped to the outside and with loads up to 29lbs the bag and I traveled comfortably up 6000 foot peaks on 8 hour, 12 mile hikes. The front shovel pocket is roomy enough for wet rain gear and the top pocket ideal for gear that is needed quickly, like goggles, shell mitts and headgear. The compression straps and front pockets allow smaller loads to be carried on day trips without the bag appearing oversize for your summer day hike, and at 3lbs 12 oz its no burden to take it along. A very robust bag that shows no signs of wear and tear after squeezing past countless spruce trees bushwhacking in New Hampshire.

Sizing Chart

All Osprey packs, save the transit bags, are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).

To determine your hipbelt size measure around your hips, not your waist. A properly fitted hipbelt rides centered over the hipbones and needs to be very snug; after all it will be carrying the bulk of the pack's weight. The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the pads when securely tightened.

Nearly all Osprey hipbelts use an exclusive ErgoPull design. It creates mechanical advantage to provide extra leverage in cinching down the hipbelt. The ErgoPull design also draws tension along the top and bottom of the belt, not through the center, so it distributes pressure more evenly over the padding and relieves direct pressure on the hipbones.

Step 3 - Harness

Osprey Crescent & Luna, Aether & Ariel and Waypoint packs offer interchangeable shoulder harnesses. Harness sizing usually corresponds to pack size, but your best bet is to try one on. A properly fit harness should terminate 2 to 3" beneath the armpit. Webbing should not touch the body. By breaking the hook and loop connection and sliding the harness up and down the backpanel the torso length can be adjusted up to 3". (see illustration).

Once you have the correct size pack, harness and hipbelt, and the torso length set properly, it's time to put some weight in the pack (20 to 30 pounds of well distributed weight will do) and dial in the fit. First, snug down the hipbelt and harness. Connect the sternum strap (A) - position it about 2 inches below your collarbones and snug it down lightly. Finally, tighten the load lifter straps to draw the load solidly against your back. The lift straps (B) should come off your shoulders at a 45 to 60 degree angle in Osprey's ReCurve and Ethereal Suspension packs. In other models these straps serve more as compression straps and ride flatter; they may even angle downwards.

In a good fit, there should be no pressure points and no gaps between your body and the pack. With Osprey's ReCurve packs, final tweaking may involve custom fitting the aluminum stays to your back.
